Beyond the Blocks. Concrete block walls, built right, offer one of the best wind resistances available for residential construction. Filling cavities in the blocks with high-strength grout or concrete mix, using the recommended psi of filler, and employing Type S mortar for strong connections are all vital aspects of reinforcing the wall.
For ultra low density hollow or solid, non- load bearing concrete blocks, their minimum compressive strength is 3.5N/mm2 or 35kg/cm2. For denser, higher weight, hollow or solid, load bearing concrete blocks, their …

Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.
Compressive strength of concrete Blocks or concrete masonry units are required to know the suitability of these in construction works for various purposes. Concrete masonry blocks are generally made of cement, …
3. Classification of Concrete Blocks. The hollow concrete blocks shall be classified in the following four types: 1. Grade 'A' These are used as load-bearing units and shall have a minimum block-density of 1500 kg/m 3. …
Cinder blocks are light-weight low-density building blocks made of cement and coal ash. Concrete blocks combine cement with sand and gravel, and a small percentage of cinders. Cinder blocks lack the strength and resistance to weather and pressure that concrete blocks possess, and aren't recommended for many load-bearing jobs.
Type N mortar mix has a medium compressive strength and is composed of one part Portland cement, one part lime, and six parts sand. Type N mortar mix is useful for above-grade, exterior, and interior load-bearing installations.

A sand cement brick is a block that contains fine aggregate and cement material in masonry construction. ... The compressive strength of sand cement brick can be presented as the performance of sand cement brick subjected to an ultimate load. The sand cement brick specimens were compressed to obtain the indirect strength of brick.
Compressive strength of concrete reduces with increased water addition. Excess water addition has detrimental effect not only on the compressive strength of concrete but also on the other concrete properties as well.
